The Camtraptions Lens Heater system helps prevent your valuable camera trap images from getting spoilt by condensation, dew formation and fogging.

The Lens Heater system consists of a programmable heating controller unit and a lens heater strip.

#### **Timer Functionality**

The heating controller has built-in timer functionality that operates on a **24-hour loop**, so the device can be left running unattended for many days or weeks at a time.

The controller can be set to provide heating during a time window when condensation is more likely to form (e.g. during the night), and turn off the heating automatically when dew formation is less likely to conserve power.

#### **Power Levels**

The controller offers three different heating power levels which allows further refinement of the power consumption.

# Accessories

When this system is being used with the <span class="s1">**Camtraptions Camera Housing**</span>, it is recommended that you use the <span class="s1">**Heated Camera Housing Window**</span> (purchased separately), for the ultimate power-efficient and focused heating solution.

# Safety Warnings

Please read these important safety warnings before using the Lens Heater.

<p class="callout danger">Important Safety Warnings:</p>

- Only use power sources within range of **6V to 18V** and rated to provide at least **1.5 Amps**.
- The Lens Heater is not a toy. Please keep out of reach of children and pets.
- Disconnect any batteries if not being used.
- The Lens Heater is **not waterproof**. Please keep it dry and do not expose to water or other liquids.
- Do not disassemble or attempt to modify the Lens Heater.

# Usage Instructions

#### **Initial Setup**

First, connect the USB connector of the <span class="s1">**Lens Heater Strip**</span> into the <span class="s1">**USB Power Output**</span> socket of the <span class="s1">**Lens Heater Controller**</span>.

Next, connect a suitable power source to the <span class="s1">**Power Input**</span> socket of the Heater Controller. The power source must have a voltage between **6V to 18V** and be rated to provide at least **1.5 Amps** of continuous current.

As soon as power is connected, the Heater Controller's LCD display will light up red and the controller will enter into the programming stage.

#### **Programming the Controller**

There are three settings that can be altered: <span class="s1">**Delay**</span>, <span class="s1">**On time**</span> and <span class="s1">**Level**</span>.

Press the <span class="s1">**M**</span> button to cycle through these three settings. A red light will glow next to the currently selected setting.

Press the <span class="s1">**▲**</span> button to increase the current setting. Press the <span class="s1">**▼**</span> button to decrease the current setting.

#### **Setting Descriptions**

<table id="bkmrk-setting-range-descri" style="width: 100%;"><thead><tr><th style="width: 15%;">**Setting**</th><th style="width: 15%;">**Range**</th><th style="width: 70%;">**Description**</th></tr></thead><tbody><tr><td style="width: 15%;"><span class="s1">**Delay**</span></td><td style="width: 15%;">0–24</td><td style="width: 70%;">Number of hours the controller should remain inactive (not heating) before heating begins</td></tr><tr><td style="width: 15%;"><span class="s1">**On time**</span></td><td style="width: 15%;">0–24</td><td style="width: 70%;">Number of hours the controller will remain active (heating) after the Delay period ends</td></tr><tr><td style="width: 15%;"><span class="s1">**Level**</span></td><td style="width: 15%;">L1, L2, L3</td><td style="width: 70%;">Heating power level (**L1** = lowest/most efficient, **L3** = highest/least efficient)</td></tr></tbody></table>

<p class="callout info">Note: The total "Delay" plus "On time" cannot exceed 24 hours.</p>

#### **Starting the Program**

Once the desired <span class="s1">**Delay**</span>, <span class="s1">**On time**</span> and <span class="s1">**Level**</span> have been set, you should not press any buttons on the Heater Controller. The heating program will commence running **1 minute** after the last button-press occurred, and the LCD display will shut off to conserve energy.

#### **Changing Settings**

If the heating program has already commenced and changes subsequently need to be made to the <span class="s1">**Level**</span>, <span class="s1">**Delay**</span> or <span class="s1">**On time**</span>, then the power source should be disconnected and reconnected to ensure that the new settings are registered correctly.

# Examples

This section provides practical programming examples showing common heating schedules for different field conditions.

# Programming Examples

### **Example 1 – Permanent Gentle Heating**

**Scenario:** The time is currently 08:33. I want the Lens Heater system to start warming my equipment immediately and to remain heating permanently (but only on a low power) until the battery is exhausted or until I disconnect the power later on.

**Required settings:**

- <span class="s1">**Delay**</span>: 0
- <span class="s1">**On time**</span>: **24**
- <span class="s1">**Level**</span>: **L1**

**Result:** After I finish entering the above settings, I press no more buttons on the Heater Controller and the time is now 08:34. At 08:35 the Heater Controller's LCD display will turn off and the system will start to provide gentle heating. The heating will be provided continuously until the power is disconnected or the battery is exhausted.

---

### **Example 2 – High Power Heating During the Night**

**Scenario:** The time is currently 14:10. I want the Lens Heater system to start warming my equipment 10 hours from now at approximately midnight and to remain heating on high power until the morning. Heating will remain off tomorrow during the day and it will switch back on again tomorrow at midnight, heating through the night again until the morning, and so on.

**Required settings:**

- <span class="s1">**Delay**</span>: **10**
- <span class="s1">**On time**</span>: **7**
- <span class="s1">**Level**</span>: **L3**

**Result:** After I finish entering the above settings, I press no more buttons on the Heater Controller and the time is now 14:11. At 14:12 the Heater Controller's LCD display will turn off, and the heating system will remain inactive for 10 hours. At 00:12 the heating will begin on high power (**L3**) and remain on for 7 hours until 07:12. Heating will remain off for 17 hours until 00:12, at which point the heating will begin again on high power (**L3**).

This 24-hour loop will continue until the power is disconnected or the battery is exhausted.
